Need some pointers on the way Laz/fpc handle gtkwidgets if possible. I am attempting (as a test) to get and then set the size and position of a Laz form using Gtk / Gdk - (not necessary I know, just leading to further things)
The Form1.Handle is a pointer to a gtkwidget - saved as 'WinHandle'. From this, I can retrieve its name, and so know I have the right pointer. How can I alter the forms size / pos using the widget handle ? TGtkWidget( PGtkWidget(Winhandle)^).allocation.width - returns garbage gtk_widget_size_request(Winhandle, @GtkAllocation) - returns 0's Working on the theory that I have to use the GDKWindow instead, TGtkWidget( PGtkWidget(Winhandle)^).Window - returns a number (no idea if its correct) but trying to use it with any GDK_Window_ procedures gives various errors (depending on proc called) Even simply attempting to get the TopLevel windows seems beyond me - gList := gdk_window_get_toplevels(); gdk_window_get_position( GDK_WINDOW(gList^.data), pXPos, pYPos); fails with 'GLib-GObject-CRITICAL - use IA__g_type_init() prior to this function though I can easily accept that my understanding of glists is built on shakey ground I know that Laz/fpc can handle most of this 'internally' for its own forms/controls - I am wanting to extend programming control outside of my app itself eg - finding xcalc by name, moving / sizing / keystrokes / etc (not just xcalc obviously) Any suggestions appreciated, as its damned frustrating knowing whats possible using Gtk/Gdk/GScreen/etc - and its just out of reach :) Thanks - SteveG _______________________________________________ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
